1. Putting Altera MAX Series in Hibernation Mode Using User Flash Memory
You can completely power down the device into hibernation mode during an inactive period. The device powers down automatically, and allows the system to power it up again when the system requires the device to execute a task, while retaining the register data.
This example application shows the capability of the supported Altera device to store the register data into the non-volatile user flash memory (UFM) before self-powering-down after an idle period. The device also reads back the data from the UFM and reloads the registers for the device to resume operation shortly after powering up.
